Abstract:
Conducting polymer can modify device surface properties and incorporate biomolecules for immobilization by electropolymerization at the same time. We investigated a method for surface modification by electrochemically deposited polypyrrole onto surface of Bio-MEMS micro device. We reported the effects of the numbers of CV cycle on the deposited film thickness and roughness in this paper. Furthermore, to prepare polypyrrole entrapment biomolecules on micro-device as a cell-culture substrate was demonstrated to promote cells adhesion.
